The National Broadband Network (NBN) is a wholesale open-access data network on a national scale in Australia. The system includes radio and wired components operated by the publicly owned NBN corporation. Retail service providers, or RSPs, work under NBN to sell access to internet services to end users. Transfer to NBN is not automatic, so you should research available providers to move your electricity, internet, and phone services in the most beneficial way possible.
History of NBN
The NBN project is the largest infrastructure endeavor in the country’s history. The rationale included replacement of the aging copper cable network and creation of a system that would meet the increasing demand for internet access across the nation. Initially proposed in 2009, the early plan for completion was 2016. This target was soon changed to 2019 and then to 2020. The original estimate for the cost of the project was around $29.5 billion, but by 2013 the cost had jumped to $46-56 billion. By late 2018, the entire project was projected to cost $51 billion. The project has been the center of political contention and an ongoing factor in elections since it was first proposed.
The NBN underwent a $4.5 billion upgrade in 2020 to increase internet speeds for 8 million residents.
Point of Interconnect (POI)
Individual RSPs connect to the NBN infrastructure through 121 POIs housed within telephone exchanges throughout the country. Transit networks transmit data from non-POI exchanges to the nearest POI.
Network Termination Device (NTD)
Customers maintain NTDs that enable interfacing with network bridges to access the NBN. Various technologies utilise different types of NTDs. Depending on the type of link used, NTDs provide several data channels with the use of an external power source.
Connecting to the NBN
You have the ability to select a NBN provider and a service plan dependent on your needs.
If you are using a fixed-line technology, your provider can let you know which of the following types you will be using:
- Hybrid fibre-coaxial (HFC) is a technology system purchased by NBN that utilises both fibre optic and CATV technologies.
- Fibre to the node (FTTN) includes a mixture of fibre optic and copper technology that is used for most NBN connections. Each node has the capability to service up to 384 homes. You will need a modem to access the network.
- Fibre to the building (FTTB), equivalent to FTTN, is used for apartments and multi-dwelling buildings with the “node” situated within the building’s communication center.
- Fibre to the curb (FTTC), once known as “fibre to the distribution point,” provides a fibre connection to a point located on the street, then extends a copper connection to the premises. Your provider should give you a network-compatible modem for access through the copper connections.
- Fibre to the premises (FTTP) provides a connection via fibre optics through the use of a passive optical network, enabling peak speeds for customers of one gigabit per second. This technology is utilised for greenfield development.
Fixed wireless technology incorporates 2,600 transmission towers using optical fibre and microwave to cover approximately 500,000 rural premises through 4G mobile broadband services. Satellite services are available for locations such as Christmas Island, Lord Howe, and Norfolk Islands that are not reached by other technologies.
Any issues with operation, repair, installation, or connection of phone or internet services through NBN should be directed to your service provider. You should note that equipment connected through the NBN will not be operational during a power outage.
In some situations, customised connections may be necessary. Your provider should work with NBN to make your home or business location serviceable in the shortest timeframe possible.
